Road Repair – Delhi Plans All-Weather Pothole Fixes With Spray Injection Technology
Road Repair – The Delhi government is preparing to introduce an advanced road maintenance system that can repair potholes efficiently in every season, including during heavy rainfall. The initiative is aimed at improving road safety, reducing travel disruptions, and strengthening the durability of repairs across the national capital.
Advanced Technology Demonstrated for Road Repairs
Public Works Department (PWD) Minister Parvesh Sahib Singh recently witnessed a live demonstration of the spray injection road patching system, a fully mechanised technique designed to repair damaged road surfaces quickly and effectively. Unlike traditional methods that often face delays during the monsoon, this technology is capable of carrying out repairs even when roads are wet.
According to the minister, adopting modern engineering solutions is an important step toward creating a stronger and more reliable road network in Delhi. He said the government is focused on improving public infrastructure through innovative technologies that offer better services and long-term benefits to residents.
Faster Repairs With Minimal Traffic Disruption
Officials explained that the spray injection system completes pothole repairs in a matter of minutes, allowing roads to reopen almost immediately after the work is finished. Since the process is carried out using a single specialised machine, it reduces the need for manual labour while minimising inconvenience for commuters.
The technology is designed to limit traffic interruptions, making it particularly useful on busy roads where prolonged repair work often leads to congestion. Authorities believe the faster turnaround time will help improve traffic flow while ensuring damaged stretches are repaired without unnecessary delays.
Fully Mechanised Process Improves Repair Quality
The repair procedure begins with high-pressure air removing dust, debris, and loose particles from the pothole. After the surface has been cleaned, a layer of bitumen emulsion is sprayed to create a strong bond between the existing road and the new repair material.
The machine then injects stone aggregates coated with bitumen emulsion into the damaged section under high pressure. This process naturally compacts the material, eliminating the need for additional rolling equipment. Officials stated that each pothole can typically be repaired within two to five minutes, allowing vehicles to use the road immediately after the operation is complete.
Longer-Lasting Solution Compared With Conventional Methods
Government officials said the spray injection method provides a more durable repair than conventional cold mix patching techniques. The bitumen emulsion securely binds the aggregate to the sides of the pothole, creating a stronger and more stable repair that can withstand regular traffic and changing weather conditions.
In comparison, conventional cold mix repairs often deteriorate within a few weeks, particularly during periods of continuous rainfall. The new system is expected to extend the lifespan of repairs for several years, reducing the frequency of maintenance work and lowering long-term repair costs.
If implemented across Delhi, the technology could significantly improve road conditions while supporting safer travel throughout the year. The proposal reflects the government’s broader effort to modernise public infrastructure by introducing practical and efficient engineering solutions capable of delivering reliable results in all weather conditions.
